4iiii Viiiiva 2.0 chest strap
The 4iiii Viiiiva 2.0 heart rate monitor is a precise heart rate sensor that shows you in real-time how your body reacts to exertion. Whether you're training intervals, running long distances, or cycling in the virtual world, you'll get reliable data for more effective training, fitness monitoring, and better recovery planning. Its durable design, long battery life, and comfortable elastic strap make it a sure bet for every movement.
In combination with the 4iiii PRECISION 3+ power meter, you get a complete overview of your performance – watts show external work, heart rate shows the body's internal response. Together, they enable precise setting of training zones and progress tracking. Outside of activity, it is recommended to detach the middle part of the strap from at least one side to avoid unnecessary battery drain.
